Installing the improver mcp mcp server

The server is distributed via npm as mcp-prompt-collector, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.

Requirements

  • Node.js: 18+ - Claude Desktop: Latest version with MCP support - macOS: Primary support (Windows/Linux coming soon)

Where it fits

Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Improver MCP sits in that group. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • Maintained by daneb, written in TypeScript.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the improver mcp mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.
